<html xmlns="http://www.w3.org/1999/xhtml" >



<script language="JavaScript" type="text/javascript" src="Move.js"></script>



<head runat="server">

    <title>无标题页</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

    <input name="Hidden_name" id="Hidden2" type="hidden" value="" runat="server" />   

    <input id="btn" onclick="a()" type=button value="按下" />

                 

        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>

    </form>

  function a()   

  {   

    document.getElementById("<%=Hidden2.ClientID>").value="456";
